Renesas Introduces SH7652, Industry's First Microcontroller Supporting Both IP Broadcasting and DTCP-IP Copyright Protection.Advanced Microcontroller with On-Chip Ethernet Controller Enables Simultaneous Transmission of Two-Channel High-Definition Digital Content over the Network SAN JOSE, Calif. -- Renesas Technology America, Inc. today announced the SH7652 microcontroller. The 200MHz SuperH[R] family device with an on-chip Ethernet controller is the industry's first to incorporate both copyright protection function for IP broadcasting(a)1 and the Digital Transmission Contents Protection Over Internet Protocol (DTCP-IP)(a)2 copyright protection standard for in-home distribution. The new device enables simultaneous transmission of two-channel High-Definition (HD) digital content over the network, ideal for digital audio-visual and office automation products that feature built-in networking functions. At 200 MHz, the SH7652 32-bit superscalar microcontroller offers 480 MIPS (Million Instructions Per Second) The execution speed of a computer. For example, .5 MIPS is 500,000 instructions per second; 100 MIPS is a hundred million instructions per second. (million instructions per second Noun 1. million instructions per second - (computer science) a unit for measuring the execution speed of a computer's CPU (but not the whole system); "4 MIPS is 4,000,000 instructions per second" MIPS ) of CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. performance and abundant processing power to handle both content protection and encryption/decryption functions for IP Broadcasting and DTCP-IP. The SH7652 features an IEEE-802.3 standard(a)4 compliant media access controller (MAC)(a)5 interface that supports connection speeds of up to 10/100Mbps and allows simultaneous transmission of two-channel HD digital content. The two-channel video stream port allows high-speed transfer of MPEG-2(a)6 TS (Transport Stream) and MPEG-2 PS (Program Stream) format data. The video stream port allows an easy interface to an MPEG-2 encoder/decoder chip, facilitating high speed network transmission of MPEG-2 TS format video data. The on-chip hardware encryption block enables high-speed encryption of content data, allowing HD digital content to be transmitted over the network with ease. An impressive array of on-chip peripherals and interfaces such as a High-Speed compliant USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. 2.0 host/function and SD memory card host interface allow seamless connections to a memory card and wireless LAN modules. Audio support is provided through the Serial Sound Interface (SSI (1) See server-side include and single-system image. (2) (Small-Scale Integration) Less than 100 transistors on a chip. See MSI, LSI, VLSI and ULSI. 1. (electronics) SSI - small scale integration. 2. ) for playback of MP3, WMA (Windows Media Audio) An audio compression method from Microsoft. Known originally as MSAudio, this proprietary format competes with the MP3 and AAC methods. WMA encodes rapidly and is known to be especially effective at low bit rates. (Windows Media([R]) Audio), and other audio formats. The SH7652 can be easily integrated into a multiprocessor system with its on-chip host interface. The SH7652 communicates with the host CPU using a 16-bit SRAM See static RAM. SRAM - static random-access memory like memory interface that provides a simple handshake for connection with the host system. CPU tasks associated with copyright protection and network processing can thus be independently handled by the SH7652 microcontroller without imposing a burden on the host CPU, simplifying the overall development process. A comprehensive range of peripheral functions is also incorporated into the sophisticated SH7652 device, including a hardware accelerator that performs TCP/IP TCP/IP in full Transmission Control Protocol/Internet Protocol Standard Internet communications protocols that allow digital computers to communicate over long distances. checksum A value used to ensure data are stored or transmitted without error. It is created by calculating the binary values in a block of data using some algorithm and storing the results with the data. computations automatically without software intervention. The SH7652 handles error-correction and encryption/decryption functions for content protection in firmware, which is provided with the device. The device also supports WM DRM10(a)3 copyright protection. Support tools are available to facilitate the system design process. Renesas offers an integrated development environment See IDE. integrated development environment - interactive development environment with software tools, evaluation boards, and the low-cost Renesas E10A on-chip debug emulator. Renesas Technology will continue to extend its lineup of products that have on-chip Ethernet controllers. Future devices under consideration include chips that will offer faster CPU performance, wireless LAN support, and enhanced peripheral functions.
